The structure of the plasma membrane makes it selectively permeable, enabling it to regulate the transport substance into and out of the cell, such as
- small, non polar molecules are hydrophobic
- Polar molecules and ions are hydrophilic
- Polar molecules and ion usually pass with the help of protein
hope this helps

Answer:
Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).
Explanation:
Nipah virus can spread to people from:
1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).
2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)
Answer:
Siamangs are arboreal,in habitat.They are species of gibbons found in the rain forest. They are skillful at moving among tree branches,their swift movement made them to escape predators.They are very noisy.
These animals are light weight because of light bones.Their head is small and round in shape.They have long arms,longer than the legs.Their body is slim.
75 of their diet is made up of fruits.They are omnivores like human thus they eat plants parts,insects, eggs of small birds etc.
They are endangered species.This is because of rapid deforestation of the rain forest habitats for developments. If 75% of their diet (which is fruits is not available)due to less fruits production, definitely they will be endangered and go to extinction from starvation as other sources of food would not sustain them.
